When writing out measurement equations in Seamly, there are many mathematical functions that one may use to make them work seamlessly. This is [to be] a list of the functions, with a one-line example of how to actually use them in equations. Functions are served by the muparser math library.<ref>https://forum.seamly.net/t/math-functions-nested-if-statement/2053</ref>
[[File:MeasurementDialogFunctionsTable.png|alt=The Functions table in the Measurement Dialog is an excellent place to find most of the available algebraic functions of Seamly.|thumb|A picture of the Functions table.]]
== Basic Functions ==
These are functions which are so basic that they didn't get included in the list
+ plus (3+4=7)
- minus (3-4=-1)
<nowiki>*</nowiki> times (3*4=12)
/ dividedby (3/4=.75)
^ to the power of (3^4=81)
== Advanced Functions ==
Most of these functions are found in the table, however there are several which depend on your ability to construct an IF function in Seamly. As such, I will discuss the IF statement, (which is not in the list,) first, & then proceed in alphabetical order as the functions appear in the list. It may be better to list them by branch of mathematics, but for now the list, & thus the alphabet, has priority.
=== IF function ===
* '''if a<b then c else d''' looks like '''( a<b ? c : d)''' in Seamly2D formulas.
* '''if e<f then f else g''' looks like '''(e<f ? f : g)'''
* When d is another test, then it looks like: '''( a<b ? c : (e<f ? f : g) )'''<ref>[https://forum.seamly.net/t/math-functions-nested-if-statement/2053/5?u=pneumarian https://forum.seamly.net/t/math-functions-nested-if-statement/2053/5]</ref>
